Project manager for the City Deal, Phill Wilson, said: “The new bypass will affect traffic movements on surrounding roads, and we are considering a number of changes to roads and junctions to take account of this.

“The changes we are looking at are designed to ensure the bypass becomes the primary route for journeys through the area, and take the opportunity to improve conditions on roads which will become quieter, such as by reducing the speed limit on Liverpool Road.

“We are planning to take these proposals forward as the bypass opens, and will carry out consultation on any proposed changes to traffic regulations.

“The bypass is a £17.5m City Deal scheme to reduce congestion through Penwortham, encourage more walking and cycling, and prioritise buses along the A59.”

The new bypass is due to be completed in early 2020.

Any changes to the roads would see the county council having to legally consult as traffic regulations would be changed.
